PLONK test (run away, run away!)

I don’t know the specifics of how or why MIDI over USB gets throttled, therefore I’m quoting someone who does.

@Psychlist1972

Over USB, each individual MIDI 1.0 message ends up as a 32 bit USB packet. In theory, USB could run at the max speed USB runs at, but in reality, most USB MIDI 1.0 devices constrain themselves to the 31250 speed due to other attached devices, etc.
